If an attacker sends a large number of SYN requests with fake source addresses, the server side will consume a lot of resources to handle this semi-connection, and saving traversal will consume a lot of CPU time and memory, not to mention retrying SYN + ACK on IP in this list. TCP is a reliable protocol, and messages will be retransmitted at this time. The default number of retries is 5. The interval time of retries is doubled from 1s to 1s + 2s + 4s + 8s + 16s = 31s respectively. After the fifth time is sent out, it will take 32s to know that the fifth time has timed out, so the total is 31 + 32=63s.1960年代末到70年代初，一个自称“十二宫”的杀人魔头是美国整个旧金山地区人民最大的恶梦。一对情窦初开的小情人初次约会的晚上，十二宫给了他们几枪，这对高中生情人就死在汽车上，自此，十二宫正式登上“历史舞台”，每天忙于杀人，几起案件下来，这个杀人魔成了整个美国最头痛的人，尤其是生活在旧金山的人民更是惊恐万分，因为从几个案件看下来，这个叫十二宫的家伙下手的对像男女老幼兼而有之，也就是说看来来有点逮到谁就干掉谁的意思。黄豆正从上房出来，看见他进来，急忙大喊道：板栗哥哥，快来，就等你了。All the people present at the position, No one has ever seen this posture, When the reaction comes back, Someone used the water from the kettle to pour Jiang Yong's small arm, It means that I want to rinse him, but the result is not bad.
